ADJUSTING SENSOR TARGET FOR POSITION AND GAP 

a. 

Verify that the ramp is completely stowed.  This establishes a reference position for ramp during 
target adjustment. 

b. 

Refer to 

Figure 4-5

 to verify that target is correctly installed on actuator driveshaft; the small stow 

segment points at the actuator and the larger deploy segment is adjacent to the pillow block.  The 
target must be laterally positioned (double-headed arrow in figure) on driveshaft so that its stow 
and deploy segments are aligned with sensors; each target segment must be directly in front of a 
sensor.  Adjust as necessary. 

c. 

Refer to 

Figure 4-6. 

 Loosen jam nuts on sensor body.  Adjust position of both nuts to achieve a 

gap between nose of sensor and outside diameter of target that is .060" 

K

.030" (gap can be set 

anywhere on outside diameter of target).  Do not allow sensor to contact target.  Tighten jam nuts 
and recheck gap.  Repeat for other sensor. 

d. 

When front edge of ramp is within approximately 10 inches of the vehicle floor, the stow sensor will 
actuate and the LED on the sensor body will illuminate.  

Figure 4-6

 shows the position of the stow 

segment when the ramp is fully stowed.
